Matrix correction and on-the-fly channel remapping

A 4-panel showing NGC 6888 in four different narrowband renderings.
Four example renderings of the same S-II + H-alpha + O-III narrowband data. Top: two examples of a 1-click SHO (HST palette) rendering. Bottom: two examples of a OHS rendering. No recompositing is needed, and detail is kept fully intact - only the colouring changed.

The Color module comes with a vast number of camera color correction matrices for various DSLR manufacturers (Canon, Nikon, Sony, Olympus, Pentax and more), as well as a vast number of channel blend remappings (aka "tone mapping") for narrowband dataset (e.g. HST/SHO or bi-color duoband/quadband filter data).

Uniquely, thanks to the signal evolution Tracking engine, color calibration is preferably performed towards the end of your processing workflow. This allows you to switch color rendering at the very last moment at the click of a button without having to re-composite and re-process, while also allowing you to use cleaner, non-whitebalanced, non-matrix corrected data for your luminance component, aiding signal fidelity.

Camera Matrix correction is performed towards the end of your processing workflow on your chrominance data only, rather than in the RAW converter during stacking. This helps improve luminance (detail) signal, by not contaminating it with cross-channel camera-space RGB and XYZ-space manipulations.

The matrix or channel blend/mapping is selected using the 'Matrix' parameter. Please note that the available options under this parameter are dependent on the type of dataset you imported. Please use the Compose module to import any narrowband data separately.
